ROOT AND STALK PULLING MACHINE.

`Specflcaton of Letters Patent.

'Application filed August 28, 1906. Serial No. 332,334.

lT all whom it may concern:

\ which the following is a full, clear, and exact zoV being shown in cross-section and other partsdescription.

This invention relates to implements for clearing the earth of stalks, roots, vines, &c.

. The object` of the invention is to produce an implementof simple construction which may be drawn along by horses and which may be easily operated by the driver, so as to dig roots or stalks from the ground.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicate correspondingparts in all the figures.. f

Figure 1 'is substantially a side elevation-of the machine, Vcertain parts being shown in cross-section, the pole of the implement being represented as broken away. Fig. 2 is substantially a front elevation of the machine, the pole and portions of the framing being broken away. Fig. 3 is a plan, certain parts being broken away. Fig.v 4 is a longitudinal section through a hub of one of the wheels, and Fig. 5 is a cross-section on the line 5 5 of Fig.` 4.

Referring more particularly'to the parts, 1 represents the frame of the implement, which may be of substantially rectangularfform, as shown, and'provided with a pole 2, having swingletrees 3, to which draft-animals may bev attached. This frame 1 is supported upon a transverse axle 4, mounted on wheels 5, as indicated. vThe construction of the hubs of these wheels and the manner of mounting the same upon the axle is very clearly shown in Figs. 4 and 5. This construction is substanltially the same as that used in attaching the wheels of mowing-machines to the axles.y The extremity of` the axle 4 is provided with a transverse slot 6, in which ake y 7 is slidably y mounted, the said key presenting beveled edges, either of which may project from the slot 6, so as to engage the teeth of a ratchet 8, formed on the'inner face ofthe hub 9, as indicated in Fig. 5. With this arrangement evidently either of the wheels inY rotating forwardly will rotate the axle, but either of the wheels may rotate rearwardly while the otherwheel is rotating forwardly, N ear the middle point of the axle 4 there is rigidly attached a bevel gear-wheel 10, and abutting against the inner face of this bevel gear- Wheel there is provided a loose hub 11, mounted on the axle, as shown. This hub is held against the face of the bevel gear-wheel 1() by a collar 12, Afixed on the axle, as will be read- I ilyfunderstood. At one side this hub 11 is provided with a bore or opening 13, in which vis rotatably mounted the inner extremity of a shaft 14, the said shaft being'provided with a bevel gear-wheell, which meshes with the aforesaid bevel gear-wheel 10. This shaft 14 extends rearward-ly, as indicated, and near its rear extremity is provided with a loose collar 16, to which there is' attached a link 17.

This link is `attached at its upper extremity Patented Apre 1e, 1907.`

to a bell-crank lever. 18, Whichis seated on the rear beam 19 of the frame 1. From the bell-crank lever a link `20extends forwardly and is attached` toan adjusting-lever 21, which is attached at its lowerextremity to a forward cross-bar 22on .the implement. This lever21 affords means forraising and lowering the rearl extremity of the shaft 14.

Upon the rear extremity of the shaft 14 `there is rigidly attached a root-puller 23, the same consisting of a wheel formed with a forwardly-projecting flange 24. The-forward edge of. this flange 'is provided with regularly-arranged teeth 25, which project vforwardly with respect to the direction of rotation of this wheel. In this connection it should be understood that `as theimplement is advancedA the shaft 14 may be rotated through the bevel-gears 10 and 15. By means of the lever 21 the wheel 23 will be lowered, so that its lower edge digs through the earth as the implement advances. Evidently the teeth 25 will operate to dig up and pull out any roots or stalks with which they come in contact.

In order to clear the teeth 25 of the roots or undergrowth which may cling to them, I

`providea wiper 26. This wiper consists substantially of4 a frame havingl substantially the formof a-Greek cross, as indicated in Fig. 2. It presentsarms 28, projecting in a plane l,at right angles to the wiper-shaft 29, upon which the frame is rigidly attached. The arrangement is'such that these 'arms 28 pass near the points of the teeth 25 and move IOO in the same direction in which the teeth project. In this way the arms engage with any projecting roots carried by the teeth and remove the same. In this connection it should be understood that the' peripheral speed of the arms 28 is greater thanv that of theteeth. Beyond the arms 28 the wiper-frame com.- prises finger-brackets 30, having rearwardlyprojecting lingers 31, the axes of which are substantially parallel with the axis of the wiper-shaft 29. y These fingers pass close to the outer or side face of the flange 24, so that they operate to assist in removing roots clinging to the teeth. These brackets are of course rigid with the arms 28 and rotate with them. The wiper-shaft 29 is conveniently mounted upon a bracket 32, attached to the frame at its rear extremity and at its forward extremityv to a transverse frame-plate '33. Upon the bracket 32 bearings 34 are mounted, in which the shaft 29 turns, as indicated. The shaft 29 isdriven through the medium of bevel gearfwheels 35, Which connect with a driving-shaft 36, the said. driving-shaft being disposed in a substantially vertical position and rotatably mounted in the bracket 32 and the plate 33. The lower extremity of the driving-shaft 36 is provided with a bevel gear-wheel 37, which meshes with a corresponding bevel gear-wheel 38, rigidly mounted on the axle 4.

To the forward portion of the bracket 32 a quadrant 39 is attached, which projects forwardly and which cooperates with the lever 21 aforesaid, so as to enable the said lever to be locked in any position desired. In this way the root-puller wheel may be held in any desired position. In order to enable the lever 21 to be locked to the quadrant, I provide locking mechanism 4() of any common construction. At a convenient point, such as on the rear extremity ofthe pole 2, a seatbe readily understood.

In using the implement evidently the wheel 23 can be raised above the ground-level when the machine is being driven to or from the field where it is to operate.

It should be understood that when the rear extremity of the shaft 14 is lowered or raised the hub 11 rotates upon the axle 4.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In an implement of the class-described, in

combination, a frame khaving a transverse axle, wheels mounted on said axle and affording means for rotating the same, a hub rotatably mounted on said axle, a shaft rotatably mounted in said hub, bevel-gears carried by said axle and said shaft for rotating said shaft, means for raising and lowering the extremity of said shaft remote from said hub, a

toothed wheel carried by said shaft and adapted to dig into the ground, a wipershaft, means fordriving the same from said axle, and a wiper-frame carried by said wiper-shaft and having arms adapted to clear the teeth of said wheel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH LEE ANDERS.
